Large telescopic combined device for bidirectional vibration control
The invention relates to a large telescopic combined device for bidirectional vibration control. The device comprises a fixed bracket, a connecting sliding plate, a cylindrical steel damping unit, a telescopic module and an anti-bending anchor plate, a horizontal sliding groove with an opening in the lower surface is formed below the fixed bracket, the connecting sliding plate is arranged in the horizontal sliding groove in a clearance manner, one end of the telescopic module is hinged to the end of the connecting sliding groove in the horizontal direction, the other end of the telescopic module is hinged to a foundation structure in the vertical direction, the connecting sliding plate is hinged to the telescopic module in the horizontal direction, and the top end of the cylindrical steeldamping unit is movably connected with the lower surface of the connecting sliding plate. The bottom end of the cylindrical steel damping unit is mounted on the anti-bending anchor plate. Compared with the prior art, vibration control in the bridge forward direction and the bridge transverse direction can be achieved at the same time, the cost advantage is obvious, the telescopic module can be customized according to different temperature displacement requirements, and the telescopic module can be practically applied to continuous beam bridges and large-span cable type bearing bridges.
本发明涉及一种用于双向震动控制的大伸缩组合装置，包括固定托架、连接滑板、柱形钢阻尼单元、可伸缩模块以及抗弯锚板，其中，所述的固定托架的下方设有下表面开口的水平滑槽，所述的连接滑板间隙置于所述水平滑槽内，所述的可伸缩模块的一端与连接滑槽端部沿水平向铰接，另一端与基础结构沿竖向铰接，所述的连接滑板与可伸缩模块之间沿水平方向铰接，所述的柱形钢阻尼单元的顶端与连接滑板的下表面活动连接，柱形钢阻尼单元底端安装在所述抗弯锚板上。与现有技术相比，本发明可同时实现顺桥方向和横桥方向两个方向的震动控制，成本优势明显，可根据不同温度位移需求定制可伸缩模块，使其可以在连续梁桥和大跨度缆索式承重桥梁中实践应用。
